On Day 3 of the Classic Iron Workout Program, we'll dial up the intensity a notch. We're doing more sets of classic exercises like barbell back squats and bench presses—except this time we'll increase the weight and work at higher intensities. Yes, that might seem intimidating at first, but if you've come this far you're definitely up to the challenge.

And by finishing off this routine with pullups and medicine ball rotational throws, this workout will also hammer your overall upper-body development and core conditioning.

Sean Collins, C.S.C.S., the head powerlifting coach at Murder of Crows Barbell Club in Brooklyn, is back to show us how it's done.

Directions:

Complete all four exercises as straight sets.

As with the previous workouts in the Classic Iron Workout Program, the main focus is building strength. The rest periods in the major lifts are fairly long, so make sure you load up a challenging weight. In the bench press and back squat, increase the weights by 5–10% compared to Day 1.
